Description

What sets the Helios apart from other Large Display Meters is its dual line display with super bright LEDs that can be read even in bright sunlight and up to 100 feet away. Based on Precision Digital’s popular line of ProVu® digital panel meters, the Helios can satisfy a wide variety of level, flow, temperature, pressure, & weight applications. It is available with models that accept 4-20 mA, thermocouple, RTD, pulse, strain gauge, AC and DC volts and current, and even Modbus®.

Go with the Helios PD2-6100 when you have a weighing application where you need to read the display from a distance, or outside in the bright sunlight in temperatures between -40 to 150°F. The PD2-6100 tare feature can be used to remove the weight of the container from the weight calculation. You can even re-transmit the weight signal with the PD2-6100’s optional 4-20 mA output.

Wall Mounting

The meter can be mounted to any wall using the four provided mounting holes. Note that the bottom mounting holes are located underneath the front door panel. To mount the meter to a wall, follow these instructions.

Prepare a section of wall approximately 11″ x 13″ (280 mm x 330 mm) for meter mounting by marking with a pencil the mounting holes (shown in the image to the right) on the wall.

Using a drill bit slightly smaller than the girth of the mounting screws, pre-drill holes at the mounting locations previously marked.

Insert mounting screws into the four mounting holes and screw them into the pre-drilled holes. Do not overtighten the mounting screws as it is possible that the enclosure could crack and become damaged.

Pipe Mounting

The meter can also be mounted to a pipe using the optional pipe mounting kit (PDA6260). This kit includes two mounting plates, two U-bolts, and the necessary nuts and bolts. To mount the meter to a pipe using the pipe mounting kit accessory, follow these instructions.

Secure the mounting plates to the top and bottom (for vertical pipes) or left and right (for horizontal pipes) of the reverse side of the meter enclosure using the provided fasteners. Do not overtighten the fasteners as it could cause damage to the enclosure.

Using the provided nuts and U-bolts, secure the mounting plates to the pipe enough torque such that the meter cannot be moved up or down (or side to side).

Application

Load Cell

A typical application for load cells is in a tank weighing operation. In the following example, this three-legged tank has a load cell under each leg. The three load cells are wired locally in parallel within a junction box. The combined signals are then connected to the Helios PD2-6100. During field calibration, the weight of the empty tank (zero point) and the full tank weight (full scale) are programmed into the meter. Over time, the tare feature on the PD2-6100 can account for obstacles like sludge buildup on the bottom of the tank when empty.

Connections Labeling

The connectors’ label, affixed to the inside of the lower door panel, shows the location of all connectors available with requested configuration.

MeterView® Pro Software

MeterView® Pro software is designed for use with ProVu, ProtEX-MAX, or Helios Series meters and allows users to remotely program, monitor, and datalog using a PC. Remote programming allows for all available meter settings to be programmed through an easy, user-friendly interface. The data acquisition feature allows the user to gather readings from a meter at user-selected intervals and generate charts using common tools like Microsoft® Excel. A linearization setup function is also included. With this utility the user can configure up to 32 linearization points and upload them to the meter. All configuration data can be saved to a file for future use. This software is accessible via the onboard USB connection on all Helios large display meters, ProVu panel meters, and ProVu-based ProtEX-MAX explosion-proof meters produced since 6 September 2016 (firmware version 4.0 or higher). In order for meters produced prior to 6 September 2016 (firmware version 3.1 or lower) to establish digital communications with a PC, a serial communications adapter is required. For an RS-232 connection, use a PDA1232 adapter.To determine the software version of a meter:
